The present study provides an overview of the diversity and distribution of grass species in Lahaul- Spiti district (cold desert) situated in the Trans-Himalayan region i.e. Himachal Pradesh, India. From the study area 141 taxa (138 species and 3 subspecies) belonging to 14 tribes were recorded. The largest tribe was Festuceae followed by Agrostideae having 48 and 20 species, respectively. Two species Poa koelzii and P. Lahaulensis are endemic to Lahaul- Spiti. Puccinellia kashmiriana is rare as per IUCN status. The present study on the grass floral wealth of Lahaul-Spiti provides an important baseline data on grasses for further quantitative and qualitative investigations like their nutritive values, crop improvement programmes and shall also help in the identification of priority conservation areas in the region.

AbstractSpiti valley is located in the Trans-Himalayan terrain of India, from where non-geometric microliths have been discovered. While the Siwalik Hills have been subjected to extensive prehistoric surveys, this is the first evidence of lithic tools discovered in the Trans-Himalayan region of Himachal Pradesh, India. Due to its topographic and intense climatic features, the Trans- Himalayan region has generally been regarded as a barrier since prehistoric times. However, Dzamathang cannot be considered as an isolated site in the Trans- Himalayas. In fact, in the adjoining areas of Ladakh, Tibet and Nepal, similar lithics have been reported from several sites and assigned to the Middle and Upper Palaeolithic. The discovery of this site suggests that the Trans Himalayan zone may have acted as a possible route instead of a barrier during human migration. Large numbers of lithics have been recovered in the Dzamathang area of Spiti Valley. Based on the collection of the artefacts from the surface, this article tries to understand the geological and geographical setting of the area, particularly concerning prehistoric settlements in the Trans-Himalayas. This assemblage consists of assorted artefacts which includes a unifacial chopper, microlithic cores, flakes, blades, bladelets, burin, and a large amount of debitage fragments. The majority of artefacts are on quartzite or quartzarenite. Future surveys will be targeted at recovering primary context sites for excavations and absolute dating.

Livestock is one of the major sources of livelihood and vital part of the agriculture and economy for the inhabitants of Cold Desert Biosphere Reserve (CDBR) in the Indian Himalayan Region (IHR). The tribal communities are dependent on plant resources for fodder to feed the livestock. The review of literature revealed that focused studies on fodder resources of the CDBR have not been carried out so far. Therefore, the present study attempts to specify 270 species of fodder representing trees (03 spp.), shrubs (24 spp.) and herbs (243 spp.). Poaceae (105 spp.) and Polygonaceae (34 spp.) were dominant families and Poa (18 spp.), Carex and Polygonum (11 spp., each), and Festuca (10 spp.) were species rich genera. Maximum species were found in the 3000 ~ 4000 m zone. Most collected fodder species from wild includes Trigonella emodii, Cicer microphyllum, Aconogonum tortuosum, Clematis ladakhiana, Cousinea thomsonii, Carex infuscata, Festuca rubra, Leymus secalinus, etc. Only 88 species were native to the Himalayan Region, 11 species were endemic and 37 species were near endemic. Ecological assessment of the fodder species using quadrate method, and rotational grazing of livestock by tribal communities and Gaddis; and development of management plan and policy briefs are suggested.

Use Efficiency

The present study was conducted in Goshal, one of the largest villages of cold desert district of Lahaul in Himachal Pradesh, India, during 2010 to 2013 to carry out photosynthetic study and water use efficiency of various species growing in the cold deserts. We classified the study area into three major ecosystems viz; Forest Ecosystem, Alpine Pasture Ecosystem and Agro- ecosystem and found that in Forest Ecosystem Salix alba was most water use efficient tree with maximum photosynthetic rate of 36.61µ mol/m2/sec However in case of Alpine Ecosystem Podophyllum peltatum (0.014534) and Artemisia brevifolia in Agroecosystem was most water use efficient species. Thus we recommend these species for Agroforestry and aforestation purpose in the cold desert area as dry land cultivation is not possible in Agro-ecosystem and for cultivated area the only source of water is through glacial melts from the upper mountain reaches.

A study was conducted to understand the plant diversity along an altitudinal gradient with elevations varying from 2750 to 5000m above msl in Lippa – Asrang valley falling in cold desert area of Pooh sub division of district Kinnaur, Himachal Pradesh during 2007. The number of tree species at 2750-3200m and 3200-3650m elevations were 10 and 8 with the dominance of Cedrus deodara and Pinus wallichian respectively. The number of shrub species were 19, 17, 7 and 3 in the elevations of 2750-3200m, 3200-3650m, 3650-4100m and 4100-4550m respectively. Juniperus communis taking shape of the dominant shrub at 2750-3200 m, 3200-3650 m and 3650-4100m elevations. Rhododendron anthopogon was the dominant shrub at 4100-4550m elevation range. The number of herb species were 76, 73, 46, 39 and 33 at 2750-3200m, 3200-3650m, 3650-4100m, 4100-4550m and 4550-5000m elevational ranges respectively. On the basis of importance value index (IVI), Artemisia brevifolia, Heracleum candicans, Thymus linearis, Bergenia stracheyi and Bistorta affinis were the dominant herbs dotting different elevational ranges and distribution pattern of plant species was mostly contiguous in all the altitudes. Index of diversity for herb species in different elevational ranges was 3.89, 3.82, 3.47, 3.21 and 2.95. Out of 78 medicinal plant species as recorded from the area, 20 species fall in the category of threatened plants. The better conservation of natural resources can be well achieved through promotion of community based conservation stressing in-situ conservation through the establishment of nature reserves and ex-situ conservation through tissue culture, developing cultivation technologies and nurseries of medicinal plants and conducting regular trainings on the procedure of medicinal plants collection, processing amongst the end users/ the local people, traders and real stake holders.

And Chemical Properties

The present investigation was carried out at village Goshal of Lahaul and Spiti cold desert district of Himachal Pradesh during the year 2010 to 2013 to compare soil physical and chemical properties by demarcating the study area into three main ecosystems viz; forest ecosystem, alpine pasture ecosystem and agro ecosystem. The soil physical properties of all the three ecosystems revealed that the soils were found nearly neutral in reaction, having no salt problem and were medium in physical status. Bulk density was more in alpine and forest ecosystem due to grazing and soil was more compact as compared to agro ecosystem. The average soil moisture was maximum in agro ecosystem. Average soil nutrient status for all the three ecosystems depicted that the fields where peas and pulses were planted were found to be possessing higher nitrogen contents than other areas due to the fixation of atmospheric nitrogen.
